5 Claims. 1

This invention relates to new and useful improvements in multiple piece template for punch presses.

One object of the invention is to provide improved means for mounting and accurately pOSitioning the individual punches of a multiple punch press at predetermined intervals with a minimum expenditure of effort and time.

Another object of the invention is to provide an improved mounting for the individual punches of a multiple punch press which includes a plurality of templates or guide members having fixed means for connection with said punches so as to position the latter in predetermined relation to one another.

A further object of the invention is to provide an improved mounting, of the character de scribed, wherein the templates have openings for receiving the locating means of individual punches with certain of the openings formed in the margins of adjacent templates whereby the spacing of the punches may be varied by employing templates of different sizes.

Still another object of the invention is to provide an improved mounting, of the character described, wherein each template has recesses in its ends for coacting with the complementary recessed ends of adjacent templates to form openings for receiving the locating means of individual punches, the openings being alined 01 ofiset as desired and being formed intermediate the ends of the templates as well as at said ends when there is some regularity of spacing.

A construction designed to carry out the invention will be hereinafter described together with other features of the invention.

The invention will be more readily understood from a reading of the following specificationand by reference to the accompanying drawings, wherein examples of the invention and wherein:

Fig. 1 is a perspective view of a portion of a multiple press with the individual punches positioned in a predetermined relation by a mounting constructed in accordance with the invention.

Fig. 2 is a perspective view of one of the templates of the mounting.

Fig. 3 is a perspective view of another template,

punches, templates are shown,

Fig. 6 is a perspective View of one of the clamps used for holding the templates in position,

Figs. 7 and 8 are plan views showing modified forms of templates, and

Fig. 9 is a plan view showing a mounting in the press bed and having a plurality of diilerent templates. 7

In the drawings, the numeral I 0 designates the bed or base of a multiple punch press having a plurality of individual punches H adapted to be actuated by a press bar or ram [2 which is reciprocal vertically relative to the bed. Each individual punch H includes a U-shaped head or bracket I 2 with its legs extending horizontally in vertical alinement and directed forwardly to ward and at aright angle to the forward edge of the press bed. A male die 13 is carried by the upper leg of each bracket and is adapted to coact with a vertically-alined female die it mounted in the lower leg of the bracket. For adjustably connecting the brackets to the bed, an inverted, T-shaped keyway or groove l5 extends longitudinally of said bed for receiving the heads of bolts I6 which project through longitudinal openings or slots ll formed in said brackets and which are fastened thereto by suitable nuts i8. Due to the keyway l5 and the slots 5?, the brackets are movable longitudinally transversely of the press bed and may be clamped in fixed positions by the coaction of the bolts l6 and nuts I 8. It is customary to position the punches H by suitable locating means, such as a cylindrical element or pin 1 9 carried by and depending from each female die It (Figs. 4 and 5). It is pointed out that the punches and their dies have not been described in detail because the same may'take any form suitable for the making of a plurality of holes in a metallic member or plate, such as indicated by the numeral 20 which has holes or openings 2| formed along its margin. Also, the

invention is applicable to other hole forming devices, such as multiple drill presses.

In order to position the punches at predetermined intervals, a longitudinal groove or recess 22 is formed in th press bed forwardly of the keyway 15. A fiat, relatively thick bar or strip 23 snugly engages within the groove 22 so as to underlie the forward end of each punch and its female die. Although openings may and have been formed 'in the bar 23 for receiving the depending pins It! so as to position the punches, said bar is relatively long and heavy so as to be difilcult to handle. Manifestly, a different bar would have to be substituted whenever it is desired to change the spacing between the punches.

Therefore, it is necessary for the user or the operator or the press to keep a large number of bars having different spaced openings on hand in order to take care of the normal demand. This difliculty is accentuated in certain industries, such as tank manufacture, wherein the spacing of itheropenings varies inzaccordanc 8. with the construction and use of the. tank.

In order to eliminate the necessity for a multiplicity of long bars, been provided and includes.a.plurality of small templates or guide members 24 which maybe mounted in a longitudinal groove or recess 25 formed in the upper surface obthe bar 6:.3- -As clearly shown in Fig. 2,each template124.includes a rectangular, fiat bar or strip which is relatively thin. A recess 26 .is -for.med.-.in--each end of the template and may be of any desired shape, being shown as semi-circular :since the pins I9 are cylindrical. When the ends of a ;pair. .of templates are abutted, the recesses 26 coactto provide an opening .for-receivingrthelo- :cating means orpins of "the punches and the length of each template determines thev distance between the openings formed by its recesses.

.Due to the smallsizeof .thetemplates, the-same may be easily formed and accurately machined. The templates havea snug fit in the groove 25 .andare adapted to be clamped in abutting, end- -to-end relationzby aclamping member or'device .21 mounted at each end ofthe bed.

The clamping device 21 includes a flat plate 28'secured by abolt 219 and nut 30 to the keyway |5.and extending forwardly of the bed. As shown in Fig. 6, a locking element or bar 3| is adjustably connected to the forward margin of'the plate 28 by suitable set screws 32. It is :noted that the 1 bar 13 l 'slidably :engages the forwardmargin of the: plateran-d. overlies thegroove 25 so as to be adjustablelongitudinally of said groove. Elongate, shoulderedopeningsor slots 33 extend longitudinally of the bar for permitting this adjustment. For engaging theendmost template, a lug or-abutment His-secured to the inner end of 'the bar3l and depends therebelow ,into'the groove 25. Adjustment of the bar isaccomplished by meansof a bo1t35:bearing-against theend ofsaid bar opposite therabutment 3,4 and threaded through an ear 36 projecting forwardly from the plate 28'. If desired,,a lock'nut 31, may be carried-by theebolt. 35. After adjust- .ment of the bolt so as to'clamp .the templates in abutting relation, the screws 32:may be;tightened to prevent displacement of thebar 3i and tits abutment? 3.4.

'Manifestly, when the templates :are confined within the groove 25 between 'a pair :of the clampingmembers 21and' the locating-pins of the punches are engaged within the openings formed by the recesses 'ML'said punchesare held in spaced, predetermined relation and the spacing between adjacent punchesmay be varied by .merely substituting a single template of differcm length. Of course, the engagement of the bolts iii-with the keyway l5 actually maintain the punche in position and their nuts are tightened after engagement of the locating means with the-openings formed by thetem- .plates. .readily positioned and changedfrom'one posi- It-is pointed out that the punches are tion-to another. In order to move-the punches. it is.only.necessary to loosen the-nuts I8 and lift .said. punches so as. todisengage the-locating; pins from thetemplateopenings. .Upon. this :disengagement,.thepunchesmaybemoved rearwardly an improved mounting has 1 aand.the ho1es"t0;b.e punchedthereby.

It is sometimes desirable to provide one or more openings in certain of the templates when there is some regularity of spacing between the openings to bepunched. A template 38, similar-to-the template-24 and having similar recesses 39 in its ends is shown in Fig. 3. An opening 40 istormedintermediate the ends of the tem- .plate r38randmaycbe evenly or unevenly spaced relative to :the :recesses 39. In other opening may be formed midway between the words, the

recesses or maybe offset from the center of the template so as to be closer to one of its ends. Irrespective of the exact position of the opening,

the template. 3.8. is .adaptedzto be employed: in-the place oftwo or morertemplates .of less length.

The use of a number of difierent lengths of .tem-

.plates -is;shown inFig. 9 as indicated by ;the

numerals. 4|, 42, 43, 44, 45, and 46. It is noted that each of these-templates has recessed ends coacting' with adjacent templates to provide positioning openings. As shown by the numeral 41, one or more of the templates may haveone or moreopenings intermediate its ends. Also,- certain of the templates maybe substantially identical or of the same length as are the templates 4 l and 44.

Although it is advantageousrto form the templates from narrow, relatively-thin stock andto mount the sameinthegroove 25 of a largebar 2.3, it is pointedcout that thetemplates maybe mounted directly inasgroove formed inthe; press bed. The templatesmay-be of the same width and thickness or may be ofqgreater width as shown inFig. -7. Templates 48 and 4-9-are shown .as being mounteddireetly in-agroove 50, similar to the groove 22, formed intheipress bed and the ends of the templates are provided with coacting recesses 5| and- 52, respectively. It is notedthat the: recesses 5! and Marc offsetlaterally 0r transversely of the longitudinal axes of the templates as well .as relative to. each other. Thus, the punches positioned by the-openings .formed by the coacting recesses would be ofiset relativeto each otherfonforming ofiset holes in plates. .If desired,.additional positioning openings 53,.54, and55 may beprovided intermediate theend 0f the templates. .Iniorder to reduce the weight. and costof the. templates 48 and 49, their thickness and the depth of thegroove 5.0 may be the same as. the. depth. of the groove 25 and. the thickness of the templates mounted therein.

In Fig. 8, a plurality of modified templates 55 are shown mounted .in a groove 5'! formed in a bar 58 similar to the bar 23 so as to be capable of being received by the groove 22'. 'The groove 51 is of greater width than the groove'25 so as toaccommodate the 'templates'56 which are .of increased width. Recesses '59 are formed in the ends of" the templates and the same are preferably offset from the center line of-the templates so as to provide ofiset openings and punch holes. One or more 'openings 60 :may be provided'intermediate the ends of each template and these :openings maybealined or offset relative 'to the end recesses and adjacent :openings.

From the foregoing, it. is .believedto be readily apparent that a. novelmounting for the individual punches of a multiple punch press has .beengpro- 'place of several short templates.

vided. The templates may be readily inserted and removed to quickly and positively position the punches in predetermined spaced relation. The templates are of chief benefit when it is necessary to frequently change the spacing of the punches. Even when all of the punches are evenly spaced, a different template or guide is necessary to vary this spacing. Irregular or uneven spacing of the punches multiplies the number of templates required. Although the present invention requires the use of a considerable number of small templates, the same may be accessibly stored and easily handled due to their small size and weight. Also, the number of small templates required is reduced by the fact that two or more templates may be used to make up a longer template as well as by the use of a template having one or more openings intermediate its ends in Furthermore, when unusual spacings are required, additional templates may be made at little cost and in a short period of time.

The foregoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as Well as in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.
